Description

Shifting fork type butterfly valve with guiding groove
Technical field
The present invention relates to the butterfly plate guide mechanism of a kind of shifting fork type butterfly valve, particularly a kind of shifting fork type butterfly valve.
Background technique
Shifting fork type butterfly valve is a kind of flat seal butterfly valve.A kind of shifting fork type butterfly valve is disclosed among the Chinese patent ZL 2,008 1 0230171.8, shifting fork type butterfly valve has valve body, the valve seal seat is arranged in the valve body, the butterfly plate that matches with the valve seal seat is arranged in the valve body, the sidewall of valve body is installed with valve shaft, be connected with the fork type driving mechanism between valve shaft and the butterfly plate, the fork type driving mechanism has in the butterfly plate front, the shifting shaft support vertical with butterfly plate, the shifting shaft parallel with valve shaft arranged on the shifting shaft support, valve shaft is connected with the shift fork vertical with valve shaft, shifting shaft is in shift fork, and when butterfly valve was opened from closed condition, valve shaft rotated, drive butterfly plate earlier along a bit of distance of axially moving of valve body outwardly, allow the butterfly plate seal ring leave the valve seal ring, drive butterfly plate then and revolve and turn 90 degrees opened butterfly valve, when butterfly valve cuts out from opening state, the valve shaft rotation, the driving butterfly is revolved and turn 90 degrees earlier, drives butterfly plate then along a bit of distance of axially moving of valve body inwardly, allows the butterfly plate seal ring be adjacent to the valve seal ring and closes butterfly valve.Turn 90 degrees in order to make above-mentioned shifting fork type butterfly valve when opening, can allow butterfly plate revolve again along a bit of distance of the axial motion of valve body earlier, can allow butterfly plate revolve earlier when closing to turn 90 degrees along a bit of distance of the axial motion of valve body, the butterfly plate of shifting fork type butterfly valve will have guide mechanism again.In the prior art, the butterfly plate guide mechanism of above-mentioned shifting fork type butterfly valve have link to each other in valve body, with the valve seal seat along the axial butterfly plate slideway of valve body, the slide block that matches with the butterfly plate slideway is arranged at the butterfly plate excircle, between valve shaft and butterfly plate front, limiting board is arranged, the location, rear end of limiting board is connected in the butterfly plate front, strip hole is arranged on the limiting board, and valve shaft is in strip hole.This shifting fork type butterfly valve is in the process of closing, butterfly plate revolves the slide block that turn 90 degrees on back, the butterfly plate and is not easy to enter very much in the interior butterfly plate slideway of valve body, slide block on the butterfly plate can not enter in the interior butterfly plate slideway of valve body, then the butterfly plate seal ring can not be close to the valve seal ring, causes shifting fork type butterfly valve to be not closed completely.
Summary of the invention
The objective of the invention is in order to overcome above-mentioned deficiency, propose a kind ofly closing in the closed procedure at shifting fork type butterfly valve, the butterfly plate seal ring is easy to be adjacent to the valve seal ring, makes shifting fork type butterfly valve close the tight shifting fork type butterfly valve with guiding groove.
The present invention is achieved using the following method.
Shifting fork type butterfly valve with guiding groove has valve body, the valve seal seat is arranged in the valve body, the butterfly plate that matches with the valve seal seat is arranged in the valve body, the sidewall of valve body is installed with valve shaft, be connected with the fork type driving mechanism between valve shaft and the butterfly plate, the fork type driving mechanism has in the butterfly plate front, the shifting shaft support vertical with butterfly plate, the shifting shaft parallel with valve shaft arranged on the shifting shaft support, valve shaft is connected with the shift fork vertical with valve shaft, shifting shaft is in shift fork, between valve shaft and butterfly plate front, limiting board is arranged, the location, rear end of limiting board is connected in the butterfly plate front, strip hole is arranged on the limiting board, valve shaft has the circular arc spacing hole of the center of circle on the axis of valve shaft on the limiting board in strip hole, an end of circular arc spacing hole is connected with the long strip spacing hole vertical with butterfly plate, valve body inner circumference location is connected with the position limit pin vertical with limiting board, and an end of position limit pin inserts in the spacing hole.
The present invention is in off position the time, and position limit pin is the outer end that is against the long strip spacing hole.
Open when of the present invention, rotary valve shaft, shift fork on the valve shaft is stirred the shifting shaft on the butterfly plate, drive the butterfly plate motion by the shifting shaft support, owing on the butterfly plate limiting board is arranged, the circular arc spacing hole of the center of circle on the axis of valve shaft arranged on the limiting board, one end of circular arc spacing hole is connected with the long strip spacing hole vertical with butterfly plate, valve body inner circumference location is connected with the position limit pin vertical with limiting board, one end of position limit pin inserts in the spacing hole, when just rotating valve shaft, butterfly plate moved along the direction vertical with butterfly plate under the constraint of long strip spacing hole before this, the equal in length of the distance of motion and long strip spacing hole, the butterfly plate seal ring is separated with the valve seal ring, and butterfly plate is at the constraint lower edge of circular arc spacing hole circular movement 90 degree then; Close when of the present invention, rotary valve shaft, under the constraint of long strip spacing hole, butterfly plate is before this along circular movement 90 degree, again under the constraint of long strip spacing hole, moves along the axial direction of valve body, and butterfly plate seal ring and valve seal cyclization also realize sealing.
On the butterfly plate of the present invention limiting board is arranged, the circular arc spacing hole of the center of circle on the axis of valve shaft arranged on the limiting board, one end of circular arc spacing hole is connected with the long strip spacing hole vertical with butterfly plate, valve body inner circumference location is connected with vertical with limiting board and inserts position limit pin in the spacing hole, spacing hole plays the effect of guide groove when butterfly valve cuts out, closing when of the present invention, guaranteeing that butterfly valve cuts out tightly.
Below in conjunction with accompanying drawing, the present invention is further described.
